jump starting with a bobcat

Let me start by saying I don't plan on doing this, but the thawing pipe conversation got me thinking.
If you were out on a job site and everyone else has left and you find out your trucks battery is dead, could you use your welding leads to jump start the truck. Obviously you would need to have it in D/C and get the lead right.
What got me thinking of this was it was -12*f and some of the semi's at work would not start. So I took my bobcat 250 out there and ran a battery charger and my torpedo heater off of it. I but plywood around the front of the truck to hold in the heat and let it warm everything up.
But I still had to use my truck to help the batteries by jumping it too. I know it would of started eventually but I had 3 more trucks to start

When I was a teenager in high school, a friend of mine got a welder to jump start his 67 Malibu with a Lincoln SA 200. The guy hooked his ground cable to the bumper, had him hold the ignition switch in the start position, He put a rod in the stinger and tapped the positive battery post. The engine fired right up. This car was already warmed up and didn't need to be turned over several times to start like a cold diesel would need, so I don't know if it would work in your case or not. Might melt down the battery post or blow up the battery if you tried it. I wouldn't try it myself.

I found this out when I let a customer plug in his cordless battery charger to my TB. I didn't even think to put it in run position first. So he plugged it in at idle & then I flipped the switch to rabbit. Several hours later my TB starts running crappy & when checked the battery was drained & not charging. Replaced the VR & all is well. Coincidence? Who knows.

At $40 a pop... those regulators could get expensive if you forget too many times...

I think most small engine shops keep a couple gross of them in stock for when suburbanites jump start their flat garden tractor batteries in the spring after they have been dormant all winter...
